Middlesbrough boss Gareth Southgate hopes to complete the signing of Heerenveen striker Afonso Alves today.
Southgate said: "There are still a few bits and pieces to be done on the deal, but I understand that it is not too far away.
"Hopefully we will get him across for a medical over the next 48 hours.
"Obviously we are aware of how many games he has played for Brazil and we expect to have to appeal. We believe that we have a very strong case and we are hopeful he will receive the work permit."
